Existing 24-105 does not have an internal focusing system making it difficult to use with polarizer and it is aways possible to change the focal point while you adjust the polarizer.

Which 24-105mm lens are you using, and if it's the Canon 24-105mm f/4L IS, when/how did you break your copy? My copy, like all proprely working copies, is internal focusing, and the front element does not rotate with focusing or zoom extension. Using a CPL in no problem - the extending portion of the barrel does not rotate at all.

Canon is confusing me..Why would they make the 24-70 f4?The 24-105 has no rivals…and if they ever discontinue that, it would be a waste..they should improve it and release a ver 2.

The 24-70 f4 is supposed to be a 6D kit and if it's alot better than the 24-105, then why would anyone buy a 5D3 kit with the 25-105 then? Whatever the price, the 2.8 version is at least 2x more expensive…i hope this brings down the price of the 2.8 version.

I really can't understand Canon's logic with this new lens…then maybe the new 5D3 will also come with this kit and it will be more expensive than the 24-105kit Good enough reason to make more $$

From the trend, I feel that Canon will slowly update all its entry primes with IS

I could see that in 1~2 years time there will be 50 f/1.4 f/1.8 IS, 85 f/1.8 IS, 100 f/2 IS

and I wonder that if they will put 135 f/2 L on IS too.

It seems from practically all responses on multiple threads on CR that IS is certainly in demand from consumers, so you could be right about future developments. If you are, then it will take the pressure off higher ISO levels as more people will be shooting at slower shutter speeds in available light thanks to image stabilization.

If those specs are true, a 0.7x max mag of the 24-70/4 is pretty darn close to a true 1:1 macro, and much higher than any other non-macro lens in the lineup (the 24-105 is 0.3x, 24-70 is 0.29x, 24-70 II is 0.21x). It's even higher than the 50mm f/2.5 Compact Macro. The use of H-IS would be consistent with that high max mag (the only other lens that has it is the 100L Macro, but PowerShots also have H-IS since they have very close MFDs).

So, this lens is a combination general purpose zoom and near-macro lens, something nonexistent in the current lineup. For people who like to shoot close ups (flowers, jewelry, etc.) this is like getting two lenses in one.

I use my 24-105mmL for product photography, and its mfd is not as close as I'd like. Since the camera is bolted to a heavy table, the IS doesn't come into play, but mfd does.I have the 100L, and I like the longer working distance, so its not likkely to go away.I can see a 2 lens travel combination of 24-70 f/4 and 70-300L being pretty handy.

I'm very glad Canon is updating the 35/2! This update is long overdue. It will be wonderful to have a small, quiet, high-quality 35 — I'm assuming it will be high quality. I hope the 50/1.4 is next on the list of updates.

+1 Or even a good 50mm f/2 USM (with IS hopefully!) would make me happy.....

The more I think about it, I do see a 50mm fast prime with USM and hopefully also IS coming up within the next 12 to 18 months..., probably sooner? A fast 50mm on a FF would be helpful for video (not that I'd use it for that.. ) I want to use is on my 7D as an equivalent 80mm fast prime....

The macro capability of the 24-70mm f/4 USM IS is a definitely bonus, and I don't underestimate how difficult that was to implement an almost 1:1 on a zoom lens like that.

But on a FF, 70mm is too short for me.... I like at least equivalent of 120mm in my walk-around lens (horses for courses). That's why the 15-85mm on my 7D is so handy, covers the focal range that I want (equiv: 24 - 136mm) in a '1 lens travel solution' - while having great IQ across the range!

I'm sure many FF users (eg 6D camera purchases) will snap up the 24-70mm f/4 USM IS, particularly if it has great IQ. It would make a great budget(ish) 'travel landscape zoom' with the 6D.

I'm not a brand-fanatic. What I do appreciate is using my 7D and 350D cameras along with a host of lenses & many accessories to capture quality photos, and share with friends.

On the mfd side, this is where you may hit issues with the 24-70 f/4L IS USM:According to dpreview.com:

This all looks great in paper, but in practice things are a little more complicated, because the working distance in macro mode ends up being only about 3cm / 1.2" from the front of the lens to the subject. At this point, you're shooting an image area of about 51mm x 34mm (2" x 1.3") using a lens with a front diameter of 83mm (3.3"), which might make lighting your subject relatively difficult.
